QSecureX – Offline-first encryption vault with no cloud or subscriptions

Summary: QSecureX is an offline encryption suite that secures text, files, and notes locally without relying on internet or cloud servers. It creates portable encrypted payloads transferable via USB, QR, or email, ensuring zero metadata and tamper detection. Currently available on macOS, it is built with Flutter for future cross-platform support.

What it does

QSecureX encrypts data locally using AES-256-GCM and generates encrypted text blocks for offline messaging. It detects any tampering with encrypted payloads and rejects altered data.

Who it's for

It is designed for users seeking offline, secure encryption without cloud dependency or subscriptions, starting with macOS users.

Why it matters

It addresses privacy concerns by enabling users to control encryption keys and perform all cryptographic operations locally, independent of internet connections or servers.
